Hi Gael
The bicep piston ruined my arm cable. Saw that we have e.g. RotCenterV3 now with ball bearings. I have modified RotGearV6 to provide channels for my signal and power cable and moved the pot holder to the inner side in RotTitV4 (provides a better angle for my cables going down).
Now I wonder about the screws, M3 nuts do not fit into the holes, M2 nuts look to be too small. What kind of screws had you in mind when designing the parts?
And how to add pictures in this message box?

no sweat but measuring the parallel distance of the nut-holes in RotCenterV3 with netfabb shows me 5.2 mm. Measuring a M3 nut by hand results in 5.5 mm. So something is wrong in my opinion (nut holes in the part are not M3 nut holes, unless there are 2 different kinds of nuts for M3?
